Connecting to VidyoConferences from VoIP Phones

If you are using a soft phone or IP phone that supports the ability to place calls directly using a SIP
dial string, you can call into a VidyoConference directly (without needing an IP PBX). The SIP dial
string must include three components:
 The voice-only service prefix of the VidyoGateway.

The extension of the endpoint or meeting room you are calling.
 The address of the VidyoGateway.
